getInitializerMethods

Will return the set of initializer method to be used when initializing
this service

The default implementation will return all methods marked with Inject
or that have a parameter that is covered by an InjectionResolver
and the InjectionResolver.isMethodParameterIndicator() is set
to true. Also, any method that has a parameter marked with
SubcribeTo will NOT be returned, as these methods are instead
meant to be called when an event is fired
